Analog Wireless Video Systems
What makes up a Trango wireless video system?
An analog point-to-point video transmission system includes a transmitter, a receiver, two antennas, and AC power adapters. Systems can be more complex depending on number of cameras, range, PTZ control requirements, etc. See our Analog Video Selection Guide for more information.
A basic Ethernet/IP video system includes a an access point, subscriber unit, and external antennas, if necessary.
How does an analog wireless video system work?
In a basic wireless video system, standard video and audio signals are input to the transmitter. The transmitter radio transmits these signals wirelessly via a microwave carrier to the receiver radio. The receiver outputs a standard video and audio signal.
Does the user require an FCC license to operate Trango Systems wireless video equipment?
No. Trango Systems' analog wireless video transmission equipment has been certified by the FCC under Part 15 regulations and require no User License. Our equipment is also certified for license-exempt use in Canada.
Do installations require line-of-sight between transmitters and receivers?
All Trango high-frequency wireless solutions, with the exception of the 900 MHz M900S, require clear line-of-sight between antennas for optimal performance. It is sometimes possible to transmit short distances through loose vegetation, but ideally, antennas should be mounted above all obstructions. For very short distances (500 feet or less), it is possible to transmit through several walls as long as they are not constructed of concrete or metal materials. Use of repeaters helps mitigate line-of-sight problems. Instead of requiring clear line-of-sight to the ultimate destination, a receiver/transmitter combo can be placed at the point of obstruction between the camera and the ultimate receiver location.
Do Trango Systems wireless products interfere with other wireless devices and vice-versa?
Our products are governed by FCC Part 15 regulations. All wireless equipment operating in the 900 MHz, 2.4 GHz, and 5 GHz unlicensed bands must adhere to Part 15 regulations. Part 15 regulations are designed to ensure that no one device can dominate the spectrum in a given area. However, to ensure that interference will not be an issue, a thorough wireless site survey should be conducted prior to installation of equipment.
Is Trango Systems equipment compatible with other CCTV, video, and sound equipment?
Trango equipment utilizes standard industry formats such as NTSC and PAL for video (color or black-and-white) and RS232, RS422, and RS485 for data to ensure compatibility with all major brands of CCTV equipment.
Is it possible to control PTZ cameras wirelessly?
Yes. Either the SDR900H, Falcon PLUS, or Eagle PLUS can be installed for the purpose of controlling PTZ cameras remotely.
What type of antennas are required?
The type of antenna will depend on the RF frequency being used and the distance needed to transmit. Therefore the farther the transmission distance, the stronger the antenna gain required for the application. See our Analog Video Antennas Guide for more information.
What is an "omni-directional antenna"?
A directional antenna transmits a signal in a particular direction towards the receiver similar to a beam of light from a flashlight.
An omni-directional antenna on the other hand radiates the radio frequency in all directions from the antenna, like ripples caused by a rock thrown in a pond.

Which type of antenna polarization should I use?
For details, read the article: Antenna Polarization and Positioning for Analog Wireless Systems.
Can I extend the length of the cable from the radio to the antenna?
Generally it is not recommended, though it depends on the cable and the frequency you are using. In general the longer the cable between the antenna and receiver the greater the loss of signal strength.
-
How far away can the transmitter be from the video camera?
It depends on the cable type. As far as the cable type will allow you before losing one volt, peak to peak. Generally RG-59 cable will allow a length of 750 feet before the video quality decreases.

What types of devices will interfere with a Trango wireless video system?
Some digital cellular phones, fluorescent lighting, and cordless phones may or may not have an effect on a 900 MHz transmitters. Microwave ovens in close proximity to 2.4 GHz transmitters can cause interference, as can other wireless products in the same ISM band (such as cordless phones or WLANs) if they are using the same channel as the Trango video transmitter.
Do specified ranges account for rain and snow which may degrade the transmit signal?
Yes, ranges specified for each product include a fade margin to account for weather conditions such as rain and snow.
